In this you could say 2.5L and 3.5L for total 6L. minus the 5L drunk and get about a liter left. in actuality:
x = 2.45 + 3.65 - 4.85 = 1.25

I would say that the estimation was reasonable.

in probability, it is equally as likely that a decimal lies between x and x.5 as it is for it to lie between x.5 and x+1. therefore when given a few numbers the rounding effect would likely round overall the same amount of points down as up. this would make it likely that the estimation would have on my an error within the amount rounded to. as you can see I rounded to 0.5 and the answer was half that

Answer from: lowkstahyna

Well 2.45 liters of orange juice plus 3.65 liters of pineapple juice would give 6.1 liters of mixed juice. His friend drank 4.85 liters of the 6.1 liters so we have to subtract 4.85 from 6.1 to get 1.25 liters remaining. It's a fairly simple straight forward question. Maybe I misread it somehow, but feel free to tell me if I'm wrong. Have a nice day!
